C++ embedded code failing on THOR

The following work unit on the HPCC University Cluster contains the C++ embedded ECL code for parsing the Bitcoin blockchain network. 

W20230526-060719 is the work unit in which the code was executed on hthor cluster. This compiled and executed as expected without generating any errors.

However the work unit W20230526-060738 containing the same failed to compile on the multinode cluster Thor. The corresponding summary images of both the work units have been attached below. 

What is the issue here, and any help would be much appreciated.
